Vaxcyte reports Q3 2026 results and positive Phase 3 data for VAX‑31

Vaxcyte announced that its VAX‑31 vaccine met all prespecified primary endpoints in the OPUS‑1 pivotal Phase 3 trial of 4,047 U.S. adults. The company said it will report results from the OPUS‑2 and OPUS‑3 trials in the first half of 2027 and plans to file a Biologics License Application in the first half of 2028. It also disclosed pro‑forma cash of about $3.4 billion as of September 30 2026, including roughly $1.1 billion raised from recent equity and convertible‑note offerings.

The trial success positions Vaxcyte to pursue a BLA for VAX‑31, potentially adding a best‑in‑class pneumococcal vaccine to the market. The strong cash position gives the company runway to fund the upcoming trials and a prospective U.S. launch. The earnings release shows a net loss of $297 million and EPS of $(1.99), reflecting higher R&D spending.
